Hazardous pressure.
Can cause severe
injury or major
property damage
from tank blow up
.
Release all pressure
and read instructions
before working on filter.
INITIAL START-UP
Be sure pump is OFF before starting procedure.
Do not operate these filters at more than 50 PSI (345 kPa) under any
circumstances!
1. Securely lock Posi-Lok™ ring in place by rotating ring CLOCKWISE until
it “clicks” past the safety latch (see Figure 3). Stop turning as soon as the
ring clicks past the latch. The ring may feel slightly loose, but it will
tighten up when pump is on and filter is under pressure.
2. Fill trap on pump with water.
3. Open air release valve on top of filter.
4. Open isolation valves.
5. Start pump to purge air from system.
6. When steady stream of water comes from air release valve, close the
valve.
NOTICE: Leaking around the Posi-Lok™ ring may indicate that the ring
is not fully locked. In this case, proceed as follows:
A. Stop the pump, close the isolation valves, and open the air release
valve to release any pressure within the filter.
B. Remove the drain plug and drain all water from the filter.
C. Push down on the top of the filter to fully seat the upper tank shell.
D. Rotate the Posi-Lok™ clockwise until it locks behind the safety latch
(see Figure 3).
E. If the ring was already locked, remove it and the upper tank shell.
Inspect and clean the O-ring and all sealing surfaces. Relubricate the
O-ring.
NOTICE: Lubricate O-ring only with the silicone grease provided or
equivalent, as other lubricants may cause the ring to swell. DO NOT
lubricate
Posi-Lok™ ring or threads on lower tank shell as this may collect grit and
make removal difficult.
After filter is operating, record filter pressure gauge reading in owner's
manual for future use.
NOTICE: When installed on a new pool, after approximately 48 hours of
operation disassemble filter and clean out plaster dust , construction debris,
etc. (see “Module Cleaning Procedure", Pages 7 and 8).
